Erin leaned over the sink, taking a deep breath. Looking into the mirror she took note of the tired eyes looking back at her, the dark circles under her blood shot eyes and her too pale, even for a Chicago winter, complexion.

In short she looked like shit. She needed a good nights sleep. Hell she felt like she could sleep for a week.

If only sleep hadn't been such an illusive bitch over the past two weeks.

Erin turned the tap and cupped her hands under the shock of cold water. A gasp coming from her lips as the cold water made contact with her pale face. The cold water doing the job that copious amounts of coffee had not done, waking her up.

She was just blotting her face with paper towel, when someone banged twice on the bathroom door.

"Lindsay, we roll out in ten minutes." She hear Atwater say thorough the door.

"I'll be out in a minute." Lindsay replied tossing the paper into the rubbish bin.

She made her way quickly down the corridor and into bullpen.

They had been working on a new case for the past eighteen hours, after stumbling upon a car accident involving heroin filled truck and two dead bodies. They had caught a break late last night after Mouse had been able to trace a warehouse back to a known associate of one of the DOA's in the truck.

After surveillance on the warehouse they were sure is was where the heroin was being moved through. And they knew they only had hours before someone came looking for their heroin filled truck.

"You good Erin?" Hank asked her is his trademark gravelly voice as she joined the rest of the team. His gaze pinned to hers.

"I'm fine." She replied quickly averting her eyes from his probing look.

"Well now I have all your attention I just wanted to go over the plan one last time." Hank told the team, giving them last minute instructions on how the take down of the warehouse would go.

Erin felt Jay's eyes on her and tried her best not to fidget under his intense blue gaze. She snuck a peek at him beneath her lashes, sighing when she saw him frowning in her direction.

Things had been slightly strained between the two partners since the decision to cool things between them had been make two weeks ago. They had always had such a good partnership and she'd be lying if she said she didn't miss him. She missed the easy banter between them. She missed their conversations. But most of all she missed falling asleep in his arms at night.

Closing her eyes she tried focus her mind on the job and not on Jay and what could have been.

She was jerked from her internal battle by a nudge to her right side, her eyes snapping open.

'Great,' she thought when saw everyone looking expectantly in her direction.

"What?" Erin asked to the room at large.

Hank stood there watching her shaking his head.

"Everyone down stairs to suit up." Hank told them and everyone started to move for the stairs.

"Not you Erin." Hank said as she made a moved to follow the rest of the team.

She stopped and turned to look at the man who was the only real father figure she had ever had. And by the look in his eyes she knew she was in for a fight if she wanted to finish this case with the rest of the team.

"What the hell is going on with you lately Erin?" Hank asked her.

"You've been distracted all week."

"Its nothing. I'm fine." Erin replied.

"Do I need to send you home, because I can't afford to have someone out there tonight who is not one hundred percent focused on the job. That's how someone ends up dead." Hank told her.

"Hank I told you I'm fine. Do you honestly think I would put the team at risk like that?" Erin asked him incredulously. Pissed off that he would even think that.

"If this is about Halstead...?" Hank started.

"Don't." Erin said angrily.

"Because this is exactly why I have rules against in house romances."

"There is nothing going on between Jay and I." Erin told him emphatically.

"Do not lie to me Erin. Blind Eddie could see something is going on between the two of you." Hank countered.

"Not any more there isn't. You saw to that." Erin said and stormed towards that stairs.

She slammed to door open nearly taking Atwater out in the process. After a mumbled apology she went to her locker and took out her kevlar vest quickly strapping it on, put on her comms radio and checked her back-up weapon and made her way out of the room.

"Alright listen up. We need to make this as quick and clean a take-down as we can. Surprise is our biggest ally tonight." Hank told them.

"I'm sure I don't need to tell you that everyone goes home tonight. Anything else is unacceptable."

"Ruzek, you and O take the east side. Dawson, you and Atwater take the west. Halstead, you and I will take the front. Roman you and Burgess wait in the back street for any possible runners Erin you and Mouse are in the van." Hank said.

"What?" Erin asked incredulously. "Are you kidding me right now?"

"Not up for discussion." Hank said looking at her and then turned away.

"What did you do to piss off Voight?" Ruzek asked her.

"Shut up Ruzek." Halstead told him.

"What?" Ruzek asked with a shrug as Alvin all but drags him to the car.

Everyone started to move towards their cars leaving Erin and Jay alone.

"What's going on?" Jay asked Erin.

"Nothing, just Hank being pissed off at me." Erin told him.

"Are you ok? You seem distracted."

"Jesus, how many times do I have to say I'm fine." Erin snapped back

Jay didn't say anything. Just stared back at her with a eyebrow raised in question.

"Sorry." Erin said letting blowing out a deep breath.

"Erin, it's me you're talking might be able to bullshit everyone else. But I know something is up with you." Jay told her.

"I'm sorry Jay..." Erin started

"Halstead and Lindsay move it now." Hank yelled at them from his car.

"Be careful tonight." Erin told Jay as they move towards the cars

"I always am. Well unless Voight shoots me in the back." He said with a grin and then he was in the car and gone.

"Are you ready Ma'am." Mouse asked from in front of the comm van.

"Mouse, I told you its Lindsay." Erin told him

"Right, sorry."

"I'm driving." She said getting into the diver side of the van.

The drive to the warehouse took about 15 minutes, and was mostly in silence. With Erin shooting down any attempt at conversation made by Mouse.

She was dying to ask him how Jay had been doing the past couple of weeks but was kinda scared about the answer. Was he doing ok and moving on. Or was he miserable like her.

They approached the pre-designated spot for the van, Erin slowed to a stop.

She and Mouse relocated to where they would oversee the comms for the duration of the bust.

"Lindsay and Mouse are you situated." Hank's voice came through loud, and well gravely through Erin's earpiece.

"Yes." Erin told him.

"Alright is everyone else in place?" He asked

After a series of replies they were all in place.

"Ok we go in on my count." Hank said

Erin knew it would be hard for her to be sidelined in the van, but as she listened to her team breach the warehouse the waiting became excruciating every second seemed like an hour. They had vision of the exterior of the warehouse but not on the interior.

"I have eyes on three suspects. All armed." She heard Jay say.

"All clear on the east side." Ruzek said

"We have another four suspects located on the west side of the building. No visible weapons." Dawson lets them know.

"Dawson, Atwater wait for Olinsky and Ruzek to get to you and take down the four suspects as quickly and quietly as you head towards the front. Halstead and I will wait for you." Hank told them.

"Burgess and Roman, hold until you hear from me." Hank said.

"Copy that." Roman replied.

Everything went silent in the van, as the team did as instructed the only thing Erin could hear was the rapid beating of her heart.

"Shit." She heard quickly followed by rapid gun fire. It seemed to go on forever.

"Intense huh." Mouse said earning a withering look from Erin.

"Two suspects down. Two on the move. On our way to you now Voight." Antonio said slightly out of breath.

"Make it quick." She heard Jay say, "We are about to come under heavy fire."

"One more down." Olinski told them.

"We lost the other one." Ruzek said

Erin jumped slightly as she heard more gunfire.

"Um detective Lindsay. We have company." Mouse said motioning towards the monitor.

Erin looked and saw a figure running towards the building next to the warehouse.

"Shit." She said then he was gone from view.

Erin didn't hesitate she jumped from the van, not giving Mouse a chance to say anything or try and stop her. Withdrawing her weapon from its holster and her flashlight she headed in the direction the fleeing figure had gone. Everything had gone quiet over her headset, the shooting had stopped.

"I'm in pursuit of suspect heading towards an outer building on the west side". Erin said into her mic.

"Erin, wait for back-up." She heard Hank say. "Halstead is headed in your direction. Wait for him."

"Hank I'm nearly there."

"That is an order Erin." Hank told her.

"I'm one minute away Erin. Wait." She heard Jay say.

She stopped by the side entrance to the building and waited for Jay to catch up with her.

"Are you trying to piss Voight off tonight." Jay asked her when he reached her.

"No that's just an added bonus." Erin told him.

"We need to go in dark. Or he will see us coming." Jay told her indicating to her to flashlight.

They made their way into the pitch black building moving together checking left and right for any sign of the suspect.

"I don't see anything. Do you?" Erin asked her partner, squinting into the dark.

"Not no far." He replied.

"He could be long gone by now." Erin said

"We need more eyes over here if anyone is free." Halstead spoke into his mic.

"I just got specs for that building and there is only the front and side door." Mouse told them.

"So where is this guy." Erin asks

"There is only one other way out of that building." Mouse said

"And that is?" Erin asked

"Up." Jay and Mouse said at the same time.

Erin moved to her left looking up, her eyes slowly adjusting to the darkness of the building.

Suddenly there was a flash of light, a bang and she was knocked to the ground, the breath knocked from her lungs, her head bouncing off the concrete floor. Then there was nothing.

The next thing she became aware of was a crushing weight on her chest and pain in her head.

"Erin." she heard from somewhere above her.

"Ouch." She said opening her eyes to see the familiar blue ones of her partner.

"Erin are you ok? Are you hit?" He asked her frantically his hands moving over her.

"Yeah by you. Did you just tackle me Halstead?" Erin asked him, still slightly dazed and a whole lot confused.

"Are ok?" He asked her again his hands framing her face.

"Ummm yeah. I think so." Erin told him

"What's going on over there?" Voight asked over the radio "Lindsay, Halstead is everything ok? We're coming in now."

"Well yeah it would be if this big lug will get off me I can't breath." Erin replied looking up at her partner, pushing his shoulders slightly trying to move his weight off her so she could breath.

Suddenly she could see the flashes of light that meant the rest of the team was coming.

"Shit." Jay said a cough

"What?" Erin asked suddenly worried by Jay's expression.

The flashes of light got closer until Voight and Antonio were standing above them.

"Shit." Antonio said when they made it to the two partners.

"A little bit of help please." Jay asked sounding short of breath.

"Jay are you ok?" Erin asked running her hands over her partner, just as he had done to her moments earlier.

"Jay?" she says again as her partner goes limp on top of her.

"Shit." Voight says this time kneeling down beside them.

"We need a bus to 1623 Wentworh. I have an officer down." Antonio says into his radio.

"Jay, open you eyes." Erin asks frantically.

"Hank where is he hit?" Erin asks

Erin doesn't miss the look between Hank and Antonio.

"Dammit Hank where is he hit." Erin asks again.

"I'm not sure kid, there he's loosing a lot of blood." Hank tells her trying find the wound.

"We need to move him now." Antonio says.

"How far out is that bus." Hank yelled into his mic.

"Five minutes." Erin heard the reply from dispatch in her earpiece.

"Jay open your eyes." Erin pleads with him, her hands on his face.

"Oh god." Erin cries out. "I think he just stopped breathing."

And with that the weight of her partner in moved off her. And rather than feeling relief at being able to breath properly again she just feels cold and a sense of loss. She would gladly never breath properly again, to have her partner breath again.

"Looks like the bullet hit him just under the shoulder blade." Hank tells them.

The rest of the team are suddenly there and everything seems to be happening all at once and in slow motion.

Hands are helping her to her feet but she cant take her eyes of where Hank and Antonio are working on Jay.

Erin tries to move towards them but its like her feet are stuck in concrete and she cant get them to move. She doesn't know which pain is the worst the one in her head or the one in her heart.

She takes a shaky step forward, knowing she must get to him. She has to get to Jay. Lights flash and then there is darkness once there is nothing.
